Member pays 300 + 4 x guest pays 19 x when are they the same? 19 x = 4 x + 300 15 x = 300 You can take it from there I think.

I will assume the maximum area is achieved with three adjacent rectangular areas with total length (end to end) = y and width = x. Total area = x * y 2y + 3x = 600 A = x * (300 - 1.5 x) = 300 x -1.5 x^2 dA/dx = 0 300 = 3x x = 100 y = (600 - 300)/2 = 150 Total area = x*y = 15,000

multiply each term by 25, the common denominator, to clean up the fractions 15k + 1100 = 12k + 200 3k = -900 k = -300 check: 3(-300)/5 + 44 = -136 12(-300)/25 + 8 = -136 Yeah!

If there are x kg of Brazilian coffee, then there are (300-x)kg of Turkish coffee. Now, work with the cost for each type of nut. They must add up to the totals cost. 5x + 8(300-x) = 7(300) 5x + 2400 - 8x = 2100 3x = 300 x = 100 So, you need 100kg of Brazilian and 200kg of ...
